"Tell us a little about the history of Horde and when and why it
started, and how you got involved. How many developers have and are
contributing to Horde?
"Horde started in summer 1998, when Chuck Hagenbuch created a
Web mail system for his university. It was called IMP 1.0.0,
consisted of about 1500 lines of PHP 3 code, HTML and
documentation. Since then, a Web application framework, over 50
applications, two groupware suites, and 350,000 lines of PHP code
have evolved. IMP still exists and has just been released as
version 4.3, while we're already working on IMP 5."
